invention rela-tes. toL means for sam? piing and observing.y or. testing the character of'liquid withdrawn from a source containingv at. least two liquidsot different charactersand. discharging at a remote point.

The invention aims to provide means whereby the chairactei ofv liquid beingfdisthawed at such remote point can .be readily determined; at a distance from the discharge fin-f`v embodiment of the invention is illustrated in fthe accoinpanying-k drawings in whichfFig 1 isa fragmentary cross-section through aportion of aship showing a pump tor discharging the bilge water overboard and' dischargingv the oil separated from. the

intern-'storage tank and having my: sampling device connected therewith Fig. is an enlarged view illustrating an embodiment of the sampling device;

F igs.V 3 o and i are diagrammatic views illustrating diliierent applications-of my de- Retcrring to the-drawings, 1.0.represents pump which is con 'nested' by' pipes y12y 'and 14. which. leady to a suitable settling tank,y not shown, or to the compartiments in a: shipcontaining a mixture oiffoili'and.water.v Fuel oil orlubricant oil frequently 'collects in` the hold oi a ship` and this mixture is sometimesy drained `into settling tanks Oris pumped directly from. the hold through'suitableqpipin and discharged overboard. It is `waste ul to dis-YV charge `this oil withfthewa-.t'erand also conltaminates'the surfaceof the water. This is particularly true *in the case of vessels navigating small rivers and harbors, and there is a considerable agitation on the part of authorities to prevent the discharge of oil vfrom ships.

In Fig. 1, I have shown the discharge pipe 16 connected to the pump 10 and with a riser 18 connected with a branc'h20 adapted to discharge the liquid overboard, this pipe being provided with the control valve 22. -The riser 18 is connected with a pipe 26 adapted to store the oil pumped` from the source containing oil and water, the pipe 24 being provided with a control valve 28. Y

In Fig. 1, I have shown a pet cock 30 connected to the lower end of the pipe 18 and arranged to discharge liquid into the sampling receptacle 32 when the pet cock is open. The receptacle 32 is carried by a.

And the liquid so colin can be observed by operator or otherattendant.,l If theisample l22 lwill be closed, and on the other hand, if the sample shows that water is` being. puirqoed,v the valve 28 will be closed.. lAfter suiic-ient taele thus.

the valve 3G; can he opened and permit the liquid to return to the sue;

tien side-'ot the-prinzip by `way ot pipe 38 will be understood. Byy properly adjustingV the pet coc-.i` 30 and theY valvey 36",.,the liquid l can continuously drip fromfthepet. cock intoV the receptacle ,32; sothatA the pump operator 26 and vice versa. opened.'

enables `the operator ip to determine the v.character neng pumped. It being; apparent.

the' pump is being pumped, the valve I liquid has collected inthe recap.

or other attendant. canV easilyy determine: at.

any time what character of pumped. l

The vessel 32-nay be of sheet metal and provided with a glass or other transparent window 33 or in some instances could be made entirely of glass or similar transparent material to permit observation of the liquid therein.

In Fig. 3, I have shown the pump 10 conliquld is being nected with a discharge riser 18EL and have shown a branch 31 connected therewith to which the pet cock 30a is secured. n The sampling device 32 is located below the pet cock andconnected by a branch 38a with the pipe 12 connected to the suction side of the pump.

Fig. 4 shows diagrammatically the applie cation of the device to any pipe line in which there is a flow of liquid and where the sainpling device 32 is installed at a point above the ultimate 'storage or delivery of the liquid. 40 represents a pipe coming from the source lli of liquid and 4Q a pipe connected therewith leading to the point ot' delivery and having a valve il to regulate the flow. lilith this arrangement a pet coclt 30h is located in a h `anch pipe 4G connected to the supply pipe 4-0 and adapted to deliver the sample o liquid into the receptacle 32 carried by a branch pipe #i8 having a regulating valve 50 therein and connected `with pipe Ll2. as shown. lith this arrangement when liquid is l'lowiiig through the pipe l0 and a sample is required, valve del is slighth1 closed and the pet cock B0 opened permitting liquid to flow through the branch ttl and into the test receptacle 3Q. The valve 50 is opened and permits the sample iiithdrawn to flow by Way 0l pipe t8 to the discharge line d2.

From the above it will be seen that my sampling device permits ol selectively conA trolling the discharge ot liquid troni a source containing liquids ol two or more specific gravities, and provides means whereinv the character of the liquid being discharged at a remote point can be readilyv determined by observation ol the liquid contained in or passing through the sampling receptacle.

The device ina)v be used in various installations where it is desirable to test or observe the character et liquid being discharged and is particularly uset'ul on board ship: as by its use l can prevent t'uel oil being dis charged overboard when the Water is com pletel)7 removed lroin either the settling tank or the hold.

From the foregoing it will be perceived that my invention provides means whereby the character ot liquid being discharged or circulated can be readiliVT determined by ohservation, and that if desired a sample ot the liquid can he withdrawn from the device and tested or analyzed. In dark locations the at tendant van roughl)i ascertain Whether oil or Awater is flowing hy merely inserting a linger in the receptacle and noting the Lt'eel.

Or he can detect the different kinds of liquids tlou'ing through the receptacle by their odor. Thus it is apparent that the chai-ad ter ot liquid can be determined by the operator using either ol the senses ol'f sight, touch or smell, and in tact the sense ol hearing can be trained to detect the di liference between dripping oil and dripping water.

llvliile l have descrilgied with great par ticul-.irityY the embodiment o't' the invention herein shown, and have illustrated the application ol the device in connection with a. discharge pump used on board ship, it is not to be construed that I ain limited to such use, nor am l limited to thc construction and arrangement shown, as variants may he adopted Without departing trein the invention as delined in the appended claims.

lll'hat l claim is:

l. ln combination with the hold of a ship, a pump adapted to 'withdraw a mixture ot bilge water and oil 'troni said hold, an oil storage receptacle, pipingl connecting the latter with the pump and including a valve controlled branch pipe 'lor discharging the water overboard` and n'ieans for Withdrawu ing a sample ot the liquid troni said piping tor olfiserralion and n'ieans for returning the sampled liquid lo the suction side ot the pump.

2. :in apparatus tor recovering the oil contained iu the bilge water ot' a ship including in combination a pump, an oil storage tank` a pipe connecting said pump with said oil storage tank, a branch in said pipe l'or discliarging bilge water overboard, valves tor controlling the flow et liquid to said tank and through said branch, means adapted to receive a sample ol" liquid Withdrawn t'roin said pipe and means for returning such saniple to the suction side o'l' the puinp.

ln Witness whereof, I have hereunto signed my naine.
